The Boss recently mistook the word "penis" for "peanuts" and has run with it ever since. This is largely because The Partner and I reinforce her behavior with raucous laughter every time she utters the word.
She has even incorporated it into her bedtime ritual with her father.
"Goodnight," The Partner will say.
"Goodnight, peanuts," she'll reply.
"Sleep well, peanuts."
"See you in the morning."
"See you in the morning, peanuts."
Always, the word is drawn out with a giggle and then emphatically expelled, the emphasis on the last syllable. "Pea-NUTS!"
Believe it or not, this reflects an improvement as it relates to her knowledge of anatomy (if not linguistics). There was a time, not so long ago, when she walked into the bathroom while The Partner was taking a shower and asked him if he was washing his vagina.
